Indian Railways Junction

Its not the gauge, the entire engineering, operating philosophy and tech is completely different than conventional rakes. Not even Japan runs Bullet trains on the same tracks, even while there are conventional train track already available between cities. Its not an administrative call but an engineering and economic impossibility.
i was thinking we can have two completely different things under same barricading so that barricading cost is reduced .......inside barricading they both can have completely different things, tracks, power input etc. May be it is impossible.
 
Indian Railways eyes corporatization of train coach, locomotive factories! Details of game-changing proposal
By: Devanjana Nag | Published: June 21, 2019 1:42:14 PM

The objective is to use the new entity to drive technology partnership and modernisation for world-standard coaches and locomotives production.

Indian Railways will conduct a detailed study of seven of its production units.

Indian Railways looks to corporatize production units! Aiming to bring in increased efficiency in production, Indian Railways is looking to hive off its rolling stock and locomotive production units and associated workshops into a new government-owned entity called “Indian Railway Rolling Stock Company”. This will be under the Ministry of Railways. The proposal is part of Piyush Goyal-led Indian Railways 100 day roadmap document for the national transporter, learns Financial Express Online. The objective is to use the new entity to drive technology partnership and modernisation for world-standard coaches and locomotives production.

According to the document prepared by the Railway Board, Indian Railways will conduct a detailed study of seven of its production units, namely, Chittaranjan Locomotive Works (CLW) in West Bengal, Integral Coach Factory (ICF) in Chennai, Rail Coach Factory (RCF) in Kapurthala, Diesel Modernization Works (DMW) in Patiala, Diesel Locomotive Works (DLW) in Varanasi, Wheel & Axle Plant in Bangalore, and Modern Coach Factory (MCF) in Rae Bareli.

Indian Railway Rolling Stock Company: Indian Railways’ big plan

Each production unit with a CEO will function as an individual profit centre, reporting to the Board/CMD of the new entity. The national transporter is of the view that the move will enable wider market access including state-of-the-art technology (modern railway coaches), superior operational efficiency and promote exports.

Indian Railways is looking to immediately start consultations with unions and will come up with a Cabinet note for the approval of at least one production unit to begin with. The project may kick off with MCF in Rae Bareli as it is a new production unit. Subsequently, all the other remaining production units will also be taken over by the Indian Railway Rolling Stock Company in a phased manner.

The MCF in Rae Bareli was declared a Production Unit of Indian Railways in July 2014 and within a month, the factory started the production of fully formed coaches. A press release issued by the Railway Ministry, earlier this year stated that under ‘Make in India’ initiative, new concepts such as extensive use of Robotics, automation etc. are also being implemented in the MCF. Moreover, new generation safer LHB coaches are being manufactured in the factory, contributing to railways and passengers safety.

Piyush Goyal-led Railway Ministry plans to send the proposal to upgrade infrastructure on New Delhi-Howrah and New Delhi-Mumbai routes to the Cabinet Committee of Economic Affairs.
railway-660.jpg

Two of the busiest routes on the Indian Railways network, Delhi-Howrah and Delhi-Mumbai are set for a massive infrastructure upgrade.

Indian Railways to reduce Delhi-Mumbai, Delhi-Howrah travel time by 5 hours! Two of the busiest routes on the Indian Railways network – Delhi-Howrah and Delhi-Mumbai – are set for a massive infrastructure upgrade in the coming years, with speeds being raised to 160 kmph on the important routes. According to a 100-day roadmap drawn by Indian Railways on PM Narendra Modi’s instructions, the train travel time on the above-mentioned routes will come down by 5 hours. The 100-day plan document of the Railway Board, seen by Financial Express Online, envisages an investment of around Rs 14,000 crore for this massive project.

Delhi-Mumbai, Delhi-Howrah trains: Travel in just 10-12 hours!

Piyush Goyal-led Railway Ministry plans to send the proposal to upgrade infrastructure on New Delhi-Howrah and New Delhi-Mumbai routes to the Cabinet Committee of Economic Affairs for approval. The project, once complete, will reduce the train travel time between New Delhi-Howrah to 12 hours from the existing 17 hours. The train journey time between New Delhi-Mumbai may come down to as low as 10 hours from the present 15.5 hours.

According to the national transporter’s estimates, Delhi-Mumbai and Delhi-Howrah routes account for nearly 30% of passenger traffic and 20% of freight traffic. While the upgradation of railway infrastructure on the New Delhi-Howrah route (1,525 kilometres) will entail an expenditure of Rs 6,684 crore, the New Delhi-Mumbai project (1,483 kilometres) will require Rs 6,806 crore.

The document states that the ambitious project will be undertaken in a fixed time, fixed cost EPC contract basis over a time span of 4 years from the date of approval. The national transporter is of the view that this format will help reduce delays and cost overrun while also ensuring better coordination and economies of scale.

Indian Railways has been upgrading its rolling stock and one of the biggest technological leaps for it was the introduction of the self-propelled Vande Bharat Express on the Delhi-Varanasi route. Banking on the success of the Train 18 project, Indian Railways is now looking to manufacture Train 19, which will be a Rajdhani Express-style sleeper variant of the Vande Bharat Express. Train 19 is being planned for the Delhi-Mumbai route with the hope of bringing travel time down.

Even as it brings its rolling stock up to world-standards, railway experts have time and again stressed on the need to invest in rail infrastructure such as tracks, signalling and fencing so that the average speed of trains on the Golden Quadrilateral can be increased. The identification of the Delhi-Mumbai, Delhi-Howrah routes for the 160 kmph upgrade is an important step in that direction.

Soon, “most powerful” WDG-6G diesel locomotive from GE to debut on Indian Railways tracks
By: Devanjana Nag | Published: June 20, 2019 2:56:57 PM

Built by GE Pennsylvania, United States, the locomotive is all set to undergo Confirmatory Oscillograph Car Run (CDCR) trials and join the fleet of Indian Railways' locomotives.

WDG-6G diesel locomotive is said to be the most powerful amongst the locomotives in use on the Indian Railways network.

Indian Railways tests “most powerful” WDG-6G diesel locomotive! Indian Railways is looking to induct the first GE WDG-6G diesel locomotive after extensive trial runs on the South Central Railway zone tracks. WDG-6G diesel locomotive is said to be the most powerful amongst the locomotives in use on the Indian Railways network. Interestingly, the GE WDG-6G locomotive for Indian Railways is also the lightest 6,000 Horse Power (HP) diesel locomotive in the world. Built by GE Pennsylvania, United States, the locomotive is all set to undergo Confirmatory Oscillograph Car Run (CDCR) trials and join the fleet of Indian Railways’ locomotives. The locomotive will be put on trials in two weeks time on the Vikarabad-Parli section, which falls on the South Central Railway zone, an official told Financial Express Online.

According to a press release issued by the South Central Railway, the induction of WDG-6G loco on Indian Railways is part of an agreement that the national transporter had made with GE for setting up a new diesel locomotive shed at Marhowra, Bihar. The agreement also includes supply of as many as 300 WDG-6G locos by GE to Indian Railways as well as to undertake their maintenance during the contract period. While the first set of locomotive will be shipped from the US, eventually GE will ‘Make in India’ the high-powered locomotives.

The locomotive is based on GE’s Evolution series and is equipped with a 16 cylinder V-16 Evolution series engine as well as a four-stroke fully turbocharged and inter-cooled machine. Compared to any other diesel locomotives in use on Indian Railways, the WDG-6G loco boasts an electronic fuel injection system for higher fuel efficiency and lower emissions. Also, the diesel locomotive is UIC 1 emission compliant, the first of its kind in the country.

The locomotive also supports various new hi-tech features related to the Driver’s Cab. The enhanced Operator and Cab amenities include the provision of HVAC (Heating, Ventilating, and Air-Conditioning), heated windshields, hot plate, urinal as well as display screens for the Loco Pilots on run to use. A Consolidated Control Architecture Control System has been placed as well with features like loco vision, trip optimizer and cab signaling with built-in future upgradability to digital solutions. Moreover, the Auto Engine Start Stop has been integrated with the Auxiliary Power Unit, giving a boost to the locomotive’s maintenance, remote monitoring. Also, diagnostics has been enabled for continuous fleet health monitoring. The front of the cab has been designed in a way to withstand tough crashes. Also, to enable easy maintenance, packaging of electrical hardware and equipment has been done optimally. However, the light weight bogie frame still requires minimal maintenance.

According to railways, with the help of this new breed of locomotives, the carrying capacity of a freight train rake will increase significantly. Also, it will enhance sectional capacities in terms of increased train services and will lead to operational efficiency in terms of fuel consumption, etc.

Railways removes 20-year-old hitch: Smoother travel now on premium trains

The last set of remaining rakes was retrofitted with this solution in South Eastern Railway. Carried out without fanfare, the job took two years at a cost of around Rs 5 lakh per coach. All rakes (trains) have now been covered.

By late April this year, the Railways managed to retrofit all its LHB stock — over 5,000 coaches, including all the 42 Rajdhani rakes. (Representational)

Two decades after the German-made Linke-Hoffmann-Busch (LHB) coaches were introduced, the Railways has managed to get rid of the all-too-familiar jolts and swaying that passengers experience while traveling on board even premium trains. The solution: retrofitting a new version of the Centre Buffer Couplers (CBC), the equipment used to link coaches in a train.

By late April this year, the Railways managed to retrofit all its LHB stock — over 5,000 coaches, including all the 42 Rajdhani rakes. Premium trains running with the LHB stock, like Rajdhanis, have been notorious for the jolts that passengers experienced, especially at high speeds and also while braking, taking away the comfort such trains promised.

From teacups spilling over to passengers being jolted from berths and even losing balance while walking in the aisles of Rajdhanis, these are among the common complaints on board these trains. For decades, they have been attributed to a fault in the couplers with no solution in sight. The unstable nature of the couplers also posed a safety issue. The issue had even led to questions being raised in both Houses of Parliament and its committees.

The solution eluded Railways for 10-15 years, Rajesh Agrawal, Railway Board Member Rolling Stock told The Indian Express. “The Rolling Stock team in RDSO, Zones and Board then reviewed the designs, technicals etc and embarked on a mission mode to eliminate jerks within six months starting in November 2018,” he said. He said premium trains including the Rajdhani and Shatabdi were prioritised to be completed by January.

“This has now been completed. Further, drivers are being counselled to use regenerative/dynamic braking at speeds above 30kmph in order to completely smoothen the draft/buffing forces. For the future, semi-automatic couplings are being planned as in Vande-Bharat express.”

The last set of remaining rakes was retrofitted with this solution in South Eastern Railway. Carried out without fanfare, the job took two years at a cost of around Rs 5 lakh per coach. All rakes (trains) have now been covered.

The retrofit solution to eliminate the jerks involved replacing the single pack draft gear or floating plate draft gear with balanced draft gear in the Centre Buffer Couplers.
While CBCs had a fault of allowing internal movement that amplified into jolts and swaying, the new balance draft gear is equipped with shock-absorbers.

The matter has been serious enough for the Railways to insert this program into its Rs 1 lakh crore Rashtriya Rail Sanraksha Kosh. (Representational Image)

Wear and tear also causes a gap between two couplers fitted together. To get rid of that, engineers have fitted shims in them. And now, the Research Designs and Standards Organisation has been asked to work on a new design of couplers that do not allow the gap to develop even after wear and tear.

In addition, train drivers are being counselled not to use air-brakes (that involve the brakes of coaches) at high speeds. Instead, they have been asked to use the dynamic regenerative braking of the engine as far as possible.

The matter has been serious enough for the Railways to insert this program into its Rs 1 lakh crore Rashtriya Rail Sanraksha Kosh or special safety fund of the government. Over the last few months, before the previous NDA government ended its term, Railways marshalled all its resources to get hold of its rakes and complete the retrofit in coaching depots across India.

Indian Railways draws up ambitious plan! All manned level crossings on Golden Quadrilateral to be eliminated

By: Devanjana Nag | Published: June 25, 2019 8:53:57 AM

Under this roadmap, which has been drawn up by the Railway Board, Indian Railways has proposed to obtain approval for the elimination of as many as 2,568 manned level crossings on the Golden Quadrilateral and Diagonals within 100 days.

The ambitious plan is a part of the national transporter’s 100-day roadmap.

Indian Railways looks to eliminate manned level crossings: In the coming years, Piyush Goyal-led Railway Ministry is all set to eliminate all the manned level crossings on the Golden Quadrilateral and its diagonals of the Indian Railways network. The ambitious plan is a part of the national transporter’s 100-day roadmap, learns Financial Express Online. Under this roadmap, which has been drawn up by the Railway Board, Indian Railways has proposed to obtain approval for the elimination of as many as 2,568 manned level crossings on the Golden Quadrilateral and Diagonals within 100 days. This will be with assured 100 per cent funding of Rs 50,000 crore from the Government of India.

The project will be implemented by Indian Railways in the next four years i.e. by 2023. In a bid to expedite the elimination of all manned level crossings on Golden Quadrilateral and Diagonals by constructing Road Over Bridges (ROBs) and Road Under Bridges (RUBs), a framework for the provision of ROB/RUB has been proposed as under:

  • Indian Railways has proposed to sanction ROBs and RUBs in a single stage at the Central government level. Moreover, the national transporter also proposes to treat the ROBs and RUBs preferably as National Projects, advising the state governments to ensure the acquisition of 100 per cent land for this purpose.
  • In its roadmap document, Indian Railways has stated that RUBs with water drainage system will be preferred as they are shorter in route and can be implemented faster. Also, RUBs require lower investments.
  • No funding from the state governments has been proposed. Thus, 100 per cent of the cost will be borne by the national transporter.
  • The document further stated the railways will require 100 per cent funding of Rs 50,000 crore from the Centre over the next four years.
  • Additionally, Indian Railways plans to eliminate manned level crossings at other traffic-heavy sections as well.
Meanwhile, earlier this year in January, Indian Railways completed the process of elimination of all the unmanned level crossings. Many Foot Over Bridges (FOBs) and subways were also constructed by Indian Railways for the public to cross the railway tracks.

IRSDC and MECON Limited have recently signed a Memorandum of Agreement (MoA) on railway station redevelopment. (IRSDC)

Indian Railways goes big on railway stations redevelopment! The Indian Railway Stations Development Corporation (IRSDC) and MECON Limited have recently signed a Memorandum of Agreement (MoA) on railway station redevelopment. Under this project, a total of eight railway stations across the country will be redeveloped including Bandra Terminus, Andheri, Chennai Egmore and Ranchi. A couple of days ago, a similar MoA was signed with two other Central Public Sector Enterprises (CPSEs) i.e., Engineering Projects India Limited (EPIL) and Bridge and Roof for the redevelopment as many as 14 railway stations including Kolkata Terminal, Hyderabad, Kalyan Junction, Ludhiana, Kanpur Central, and Udaipur City.

According to a press release issued by the IRSDC, these CPSEs will come up with Detailed Project Reports (DPRs) of these 22 railway stations for their development/redevelopment and also they will act as Project Management Consultant to IRSDC for implementation of the above-mentioned station redevelopment program. The move is being considered to be a great milestone in the government’s prestigious program of station redevelopment, it stated.

Under this program, six CPSEs have been selected by IRSDC for the redevelopment of as many as 41 railway stations across India. The remaining CPSEs who shall also be signing a similar agreement with IRSDC shortly are RITES, IRCON and NPCC. The move is expected to further accelerate the station redevelopment initiatives that are being undertaken by the IRSDC.

The IRSDC, which is a Special Purpose Vehicle (SPV) under the Ministry of Railways is also transforming several other railway stations into swanky airport-like hubs. In the coming years, the stations – Anand Vihar, Bijwasan, Chandigarh, Shivaji Nagar, Surat, Biayyappanahalli, Nagpur, Gwalior, Amritsar, Gandhinagar (Jaipur), Sabarmati, Kanpur, Thakurli, Habibganj and Gandhi Nagar (Gujarat) will undergo a massive renovation. The stations will be provided with multiple modern facilities and amenities for the convenience of passengers. The redevelopment work in Habibganj and Gandhi Nagar stations as India’s first airport-like world-class hubs is already in progress.

I don't know quite if the gauge is the same i.e - the tracks for Train 18/20 is the same as the Bullet Train. I've often wondered why is it that we haven't / aren't going in for tracks suitable for Bullet Train speeds of 500-600 kph. As it is we're behind the curve. What happens if 20 years down the line we decide to go in for an upgrade? Do we have to re lay these tracks or do we go in for another setup altogether. Consider the Konkan Railway. In some streches it still is a mono track system. Imagine the money IR would be spending if they were to go in for an expansion again. Do the IR actually plan for 40-50 years in advance or do we hear the same drivel of inadequate funds?

I hope someone in the know casts some light on this. @anant_s ; @Amal

It is technically and economically impossible to have trains running at that speed and again that is a direct engineering issue and even if such train is made it will be cost prohibitive to operate.

If I'm not mistaken the Bullet train in Japan has already crossed speeds in excess of 400 kph, 2 decades ago.

I read somewhere they were aiming for a speed of 500-600 kph this decade. Whether it was thru this technology or Maglev, I'm not sure.

Japan is planning to introduce trains at 360 kmph only in 2030. Currently China is operating trains at 350 kmph. The biggest issue in increasing the speed is air resistance and the only alternate to go beyond 400 kmph will be hyper loop, though the commercial viability is questionable.

The article says they've already tested a MagLev version @603kph in 2015. For all you know it wasn't only for experimental purpose. I know think I read about this around the time they've tested the MagLev version. No clue about the economics of it.

Besides Hyperloop is still in an Experimental stage and the speeds it runs at makes sense for longer distances, namely inter state rather than intra state, though initially the first line proposed in India is an intra state one.

MAGLEV is not commercially viable. Even the French TGV has tested 574 kmph in 2007. But these speeds are not practical for commercial usage.
 
Why not? Can you elaborate?
Normally the test speeds are for a very short duration and test tracks are straight. It's not practical to have a track completely straight from source to destination. Next important reason is the safety issue. As speed increases probability of failure of mechanical parts will exponential rise. So far non of these trains have proven their speed on a sustained manner over long distances. Even the Japanese are taking more than 10 years to bring it to commercial usage even after top speed of 400kmph is already proven and yet choosing to operate at 360 kmph. Third reason is commercial aspect of it. The energy consumption will be very high to overcome the wind resistance and won't make commercial sense, just like concord.

Maglev. but even maglevs have not been commercially viable. Let me elaborate. There are two challenges while operating at high speeds, saftey and technical (cost of running).

Safety : By far the biggest factor.
  • When you have a conventional train running at high speeds the driver has to be quick to react to challenges.
  • Human response time is slow to respond to any kind of abnormality at 600kms an hour
  • Imagine a Bird or a tiny stone in the path of a train travelling at 500-600 kmh, that is explosive energy.
Technical :
  • The wheels have to take a beating and when the train is at 500-600 kmh imagine the centrifugal stresses acting on the wheels and the force on the tracks, both have to made to with stand those stresses. and that too.. without fatigue. No one wants to change al wheels on a train after 5-6 runs.
  • Track life for the above reason, metal fatigue.
  • Energy : while you can run trians fro high speeds 550+ or even 600 for record runs but not for commercial operations, the air resistance increases (D = Cd * A * .5 * r * V^2), also in terms of Kinetic energy, the train has to expend the ~sqared the amount of energy for every unit increase in velocity this is a quadratic relationship. so the energy costs (and there by operating costs) increase by 4 times if velocity is increased by 2 times add the energy lsot to drag that also increases, then there is the vibrations of the machine. The costs are just insane...
  • Trivia : Planes fly in the stratosphere where there is very less air so very less drag and very little chance of bird hit (except during landing and takeoff)
Taking all things into account 320 kmph is found to be maximum allowable operating speed even in the very latest Shinakaen and HSR trains.

Just another query. The technical aspects ( wheels & track life) would apply to a bullet train running on rails not to MagLev trains, if I'm not mistaken. Secondly, AI ( driverless technologies) and enclosing the entire length of such a MagLev train to account for the safety factor can be possibilities which can be considered in the future as such technologies develop leaving only the commercial viability vis a vis energy consumption to be vaildated.
